Hemangioblastoma radicular extraforaminal de la raíz L4 derecha / Hemangioblastoma of the right L4 nerve root with radicular extraforaminal involvement

Los hemangioblastomas son tumores benignos, hipervasculares, cuya localización más frecuente es a nivel de la fosa posterior o la médula espinal. Los hemangioblastomas radiculares representan menos del 2% del total. Presentamos el caso de un paciente con un cuadro de dolor radicular en el territorio de la raíz L4 derecha a consecuencia de un hemangioblastoma radicular dependiente de dicha raíz. El diagnóstico primario de esta patología suele ser erróneo, sospechándose esta entidad únicamente durante el acto quirúrgico. Dada la gran vascularización que presentan, es aconsejable intentar una embolización prequirúrgica para disminuir así el sangrado intraoperatorio y evitar lesiones en raíces elocuentes. En nuestro caso, tras la devascularización del tumor y bajo control neurofisiológico, se consiguió una extirpación completa de la lesión sin evidenciarse déficit neurológico posterior

Hemangioblastomas are benign hypervascular tumours, which are frequently located at the posterior fossa or the spinal cord. Nerve root hemangioblastomas account for less than 2%of total cases. Sometimes the initial diagnosis can be inaccurate and the final diagnosis is not reached until the surgical procedure is performed. Given the high vascularisation of this particular kind of tumour, preoperative embolisation of the tumour is recommended to reduce surgical bleeding and minimise the risk of injuries to motor nerve roots. In this particular case, the patient presented with radicular pain in the right L4 nerve root territory originated by a radicular extraforaminal hemangioblastoma. After tumour devascularization and under neurophysiological control, total excision of lesion was achieved without posterior neurological deficit

Plasma membrane sterols are involved in yeast's ability to adsorb polyphenolic compounds resulting from wine model solution browning.

The aim of this work was to demonstrate the direct interaction between membrane sterols of yeast lees and some polymerized phenolic compounds resulting from wine model solution browning. For this purpose, we first demonstrated by measurement of steady-state fluorescence anisotropy of the cationic fluorescent TMA-DPH probe the effect of polymerized compounds from the model reactions of (+)-catechin/acetaldehyde and (+)-catechin/glyoxylic acid on the plasma membrane order of Saccharomyces cerevisiae yeast lees enriched with different sterols. In a second set of experiments, we used S. cerevisiae plasma membrane vesicles spiked with different sources of sterol (ergosterol, cholesterol or a mix of grape phytosterols) to assess the effect of the same polymerized compounds on both vesicle integrity and membrane leakiness to protons by ACMA fluorescence. All the obtained results prove that yeast membrane sterols are able to strongly interact with some polymerized compounds resulting from the browning of model solutions, likely explaining the yeast ability to adsorb polyphenolic compounds and mainly the colorless intermediate compounds of the browning reactions.

Effect of different yeast strains and their culture conditions on the prevention of wine model solution browning by yeast lees.

The purpose of this work was to examine the possible involvement of yeast membrane components in the adsorption of browning compounds from oxidized white wine. For this purpose, different yeast strains and growth conditions (aerobiosis and anaerobiosis) were tested for their ability to prevent browning of two model solutions consisting of (+)-catechin/acetaldehyde and (+)-catechin/glyoxylic acid. The obtained results showed that the effects of yeast lees are different according to the type of the studied model solution and the growth conditions that affect both the quantity and the quality of membrane sterols of the yeasts. Moreover, in vitro experiments proved that yeast membrane sterols could be likely involved in the yeast's ability to adsorb polyphenolic compounds and mainly the colorless intermediate compounds of the browning reactions.

Retention of browning compounds by yeasts involved in the winemaking of sherry type wines.

Wine model solutions were used to study the ability of dehydrated yeasts to retain the brown products formed in the reaction between (+)-catechin and acetaldehyde. Saccharomyces cerevisiae races capensis and bayanus, two typical flor yeasts involved in the biological aging of sherry wines, had a higher capacity to retain coloured compounds than S. cerevisiae fermentative yeast. Of the flor yeasts, capensis exhibited a higher colour reduction capacity than bayanus. Such differences may account for the different rate at which browning compounds are removed at different times of year during the biological aging of wines.

Utilización del masaje en el cuidado de los mayores como técnica terapéutica y forma de comunicación a través del proceso de enfermería / Use of massage as a therapeutic technique in elderly people caregiving and as a way of communication through the nursing process

Se ha comprobado que la comunicación basada en el contacto humano y la afectividad forman parte de las necesidades básicas de la persona. El acto de tocar puede producir un gran impacto en la respuesta del anciano a una situación determinada. El masaje simple, la acupresión y la reflexología son actividades que están basadas en el tacto y demostradas científicamente como válidas, por lo tanto deben estar integradas en el proceso de enfermería, formando parte de un cuidado integral y holístico en los mayores ya que, de forma natural, puede ayudar a mejorar los problemas físicos y/o emocionales que se asocian al proceso de envejecimiento. En el Catálogo de intervenciones de Enfermería (CIE) el masaje simple y la acupresión están considerados como intervenciones propias de enfermería e incluidas en algunos diagnósticos. Por las características del proceso de envejecimiento, consideramos que se debe incluir la realización de la reflexología y especificar el tipo de masaje además de ampliar en todas su uso a otros diagnósticos enfermeros que aparecen con frecuencia en la persona de edad avanzada, para aplicarlas en nuestra práctica diaria como parte del cuidado

It has been proved that communication based on human contact and its affectivity is part of basic human needs. The act of touching can have a great impact on elderly people response to a certain situation. Simple massage, acupressure, and reflexology are activities based on touch had proved as scientifically valid. According to this, they have to be integrated into nursing processes, being part of the comprehensive and holistic care of elderly men for it can help naturally to improve physical and emotional problems associated with the process of aging. In Nursing Interventions Classification (NIC), simple massage and acupressure are considered to belong to Nursing, and included in some diagnoses. Taking into consideration the characteristics of the process of aging, we considered that reflexology’s realization must be included, and that the kind of massage must be extended to other nursing diagnoses, which usually appear in elderly patients, as to be used in daily life as a part of the care (AU)
